Rose plant named ‘POULen010’

ABSTRACT

A new garden rose plant of the hybrid tea class which has abundant, deep pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULen010’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between anunnamed female parent plant, and a male parent ‘Harmusky’, non-patented.The two parents were crossed during the summer of 1996 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety is named ‘POULen010’.

The new variety may be distinguished from its seed parent, by thefollowing combination of characteristics:

-   -   1. Whereas seed parent has a light pink flower color,        ‘POULen010’ has a light red to a deep pink flower color.    -   2. The seed parent has a 10 to 20 petals. ‘POULen010’ has 50        petals.    -   3. The seed parent has little to no scent, while ‘POULen010’ has        a strong, floral scent.

The new variety may be distinguished from its pollen parent, ‘Harmusky’by the following combination of characteristics:

-   -   Whereas the pollen parent has a medium pink flower color,        ‘POULen010’ has a light red to deep pink flower color.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant deep pink flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots;    -   3. Disease resistance;    -   4. Exceptional fragrance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘POULen010’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter 1996 and conducted evaluations on the resulting seedlingsin a controlled environment in Fredensborg, Denmark.

‘POULen010’ was selected in the spring 1997 by the inventors as a singleplant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULen010’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in June, 1997. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULen010’ are true totype and are transmitted from one generation to the next.
